Compare and contrast convergent and divergent evolution.
Compare and contrast convergent and divergent evolution.
Marking-scheme solution
Differences
Similarities :
$\displaystyle \star$both are influenced by the environment
$\displaystyle \star$both contribute to species evolution.
| Divergent evolution | Convergent evolution |
| Divergent evolution occurs when same structures developed along different directions due to adaptations to different needs | Convergent evolution occurs when different structures evolving for the same function and hence having similarities |
| Divergent evolution produces homologous structures. | Convergent evolution can result in analogous structures |
| It indicates common ancestry | It indicates similar habitat has resulted in selection of similar adaptive features |
